Method for reducing emissions of harmful substances in gas turbine engine

FIELD: engines. SUBSTANCE: invention relates to aircraft engineering and can be used to control a gas turbine engine. Method of reducing emissions of harmful substances comprises additionally measuring fuel pressure in standby Rt 1 and main Rt 2 combustion zones, calculating ratio Rt 1 /Rt 2 , comparing measured values of emissions of harmful substances with maximum allowable values and correcting pressure ratio Rt 1 /Rt 2 by reducing fuel supply into standby combustion zone until level of harmful emissions is 1-2 % lower than maximum permissible values. EFFECT: invention improves ecological indices of emissions of harmful substances during operation of gas turbine engine. 1 cl, 1 dwg
